Lids for beverage containers

ABSTRACT

The invention relates to lids for beverage containers and related methods, for example, a lid to fit within the screw on compression assembly found on standard canning jars to adapt the container to improve a user&#39;s ability to consume liquids directly from the vessel. Lids according to certain embodiments of the invention can be used with a wide range of containers like jars, so that the containers can be conveniently used to consume a beverage while avoiding spilling and facilitating extended use and recycling of the containers.

This application claims the benefit of U.S. Provisional Application No. 61/630,616, filed Dec. 15, 2011, which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The invention relates to lids for beverage containers, preferably used with a compression system like a screw-on ring or a band.

BACKGROUND

Many consumers seek to reduce the amount of refuse they produce, or to reduce their carbon footprint, a measure of the total impact of their lifestyle. One way to reduce refuse and lower carbon footprint is to recycle. In addition, recycling allows customers to save money. These goals can be pursued by not throwing away jars. The re-using of jars as drinking cups allows a customer to save both money and help reduce their carbon footprint.

Owing in part to the increase of the “green” market, and in response to the need for alternatives to the disposable cup or bottle, there has been growing interest in re-usable drinking cups. Aluminum and steel premium water bottles and drinking cups are not a practical alternative because they cost considerably more than disposable cups. Canning jars have a widespread use in households worldwide and they are widely available. The most common class of canning jars is the ubiquitous Mason jar, discussed in John L. Mason's Patents U.S. Pat. No. 22,129 and U.S. Pat. No. 22,186. Different variations of Mason jars have been used, and the term “Mason jar” has become a name for canning jars.

It would be desirable to have better ways to use jars and other containers for consuming beverages in order to use those jars and containers rather than adding them to refuse, and to save the cost of obtaining durable containers for beverage consumption. The present invention provides such technology by providing lids that can turn a jar, or a range of other containers, into drinking cups.

SUMMARY OF THE INVENTION

The current invention, in certain embodiments, relates to articles of manufacture and methods for using a container for consuming beverages. In certain embodiments, a device of the current invention is a lid that fits on an opening in a container holding a liquid. In certain preferred embodiments, a lid of the current invention comprises a hole to facilitate removing fluid from a container on which the lid is used. In certain other embodiments, a lid of the current invention comprises a second hole to facilitate air-flow through the lid, for example while liquid is removed from a container on which the lid is used through the first hole in the lid. In certain preferred embodiments, liquid can be removed from a container through a lid of the invention without removing the lid from the container, for example by drinking a liquid through a hole in the lid of the invention.

In certain preferred embodiments, a lid of the current invention is used with an attachment system, for example a screw-on compression system or an elastic or adhesive attachment system, to hold the lid in place on a beverage container, for example a canning jar. An attachment system for use with a lid of the invention, in certain embodiments, is capable of attaching a lid to a beverage container in a reversible manner, for example during use of the beverage container for consuming a beverage.

A lid of the current invention, in certain embodiments, can be used with a jar, a glass, a bottle, a cup, a mug, a beaker, a jug, a pot, a pitcher, a carafe, or any other container useful for a beverage.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to lids for food containers, preferably containers for liquids for consumption by people. In certain preferred embodiments, a lid of the current invention fits onto an opening in a container so that it seals the opening. In certain other embodiments, a lid of the current invention comprises a hole for removing liquid from a container, for example, a hole for drinking, for pouring, or for inserting a straw. In certain other embodiments, a lid of the invention comprises a hole for allowing air to enter and escape the container on which the lid is used. In certain preferred embodiments, a lid of the current invention is attached to a container through some means of attachment suitable for the container, for example, a screw on ring, an elastic band, or some other means. In certain preferred embodiments, a lid of the current invention is usable for food and beverages for human consumption. In certain other embodiments, a lid of the current invention is useful for use by an animal, for example, a small animal, a pet, or a farm animal. A lid of the current invention can be used with any container useful for holding liquids for consumption, for example, a jar, a glass, a bottle, a cup, a mug, a beaker, a jug, a pot, a pitcher, a carafe, or any other container useful for a beverage.

In certain embodiments of the invention, a replacement lid is provided, which is held by a screw-on compression band to the top of a Mason or canning jar. This application describes a novel device which replaces the removable disc in the typical two-piece lid or cover assembly for a canning jar, with a ergonomically designed spout and opening, converting the jar and cover assembly into a portable drinking vessel. The device utilizes the locating and securing technique provided by the screw-on compression band, much like the standard disc cover for the glass canning jar or Mason jar.

While the replacement lid, in its preferred embodiments, relates to drinking beverages such as coffee or iced tea from a Mason jar, the replacement lid has broader applications. The present invention encompasses a novel method for a drinking cup, for Mason jars and canning jars in general. Additionally the present invention relates to a novel construction of lids for beverages and novel methods for using the lid with different types of jars and for different beverages. The novel construction of the replacement lid provides other advantages that are not necessarily related to re-using Mason jars, as will be evident from the description set forth below.

The present invention relates to replacement lids for jars, especially lids for jars in home use, and particularly to lids for Mason jars where the lid allows the user to drink from the jar by sipping or pouring from an open portion of the lid. Typically jars include jars packed with fruits or vegetable, a particular version of a jar is called the Mason jar, a jar that is commonly found with a threaded lip for screwing on a metal lid with a threaded lid fastener. The lid fastener screws to the top of the jar and compresses the metal lid to the lip of the Mason jar, sealing the contents inside. The metal lid fastener may be of a variety of designs, from clamping to screw style, with and without a rubber gasket. Canning jars come in two standard sizes, Wide Mouth, and Regular Mouth. These two standard sizes are used in the United States and are also used in other countries. Jar sizes are determined by the internal diameter of the mouth opening of the jar. Canning jar size is independent from the jar capacity. Canning jars are available in a variety of different capacities, making them ideal for transporting a variety of different types of beverages and foods.

A lid of the current invention, in certain embodiments, is placed on top of the metal seal disc that comes with a beverage container, for example a canning jar, so that the stack would be, from the bottom, a canning jar, a metal disc, a lid of the invention, and then a compression ring, whereby the beverage is sealed, for example, for travel. In this embodiment, when a user wants to open the jar and drink using the lid of the invention, the metal seal disc is removed.

Commonly used canning jars with a threaded lip have a screw-on ring compression system used to secure a lid in place. These jars make ideal portable containers as they are relatively abundant, cheap, thermo-resistant, and made from food-grade recyclable glass. Using these unmodified containers for beverages is difficult because the screw clamp must be removed and resealed every time the user wishes to drink. The threads on the outer surface of the canning jar interfere with a person being able to make a watertight seal with their bottom lip because they are not smooth, and not comfortable to drink from. Further, it is difficult to drink from these containers because their opening, or mouth, tends be quite wide.

The present invention provides an improvement on the lid of the jar, by replacing the conventional lid with a version designed with an opening that allows a person to drink, eat or pour from the jar. In one example the replacement lid of the invention allows the jar to be an environmentally friendly alternative to disposable coffee cups, the jar is re-used to drink coffee from a coffee sipping lid fixed to the top of the jar by the lid fastener normally used on a Mason jar.

In certain embodiments, the invention provides bento box separators, for example for use with container, for example containers like jars. A bento box separator, in certain embodiments, is inserted into a beverage container, for example a jar, so that it separates the contents of the separator from the contents of the remainder of the beverage container. A bento box separator can be used, for example, to maintain different components in a beverage container separated, for example to separate a dry component from a wet component, or a sweet component from a non-sweet component.

In certain embodiments, a lid of the invention is in the shape of a baby nipple, preferably with a hole for removing liquid at the tip. In certain embodiments, a nipple shaped lid of the invention includes a hold to facilitate the equilibration of air, for example to allow air to enter a beverage container while fluid is removed.

In certain embodiments, a lid of the invention includes a protrusion that may be used to obtain juice from fruit or vegetables, for example by pushing the fruit or vegetable onto the protrusion. A lid according to these certain embodiments can be referred to as a juicer lid or fruit juicer lid or citrus juicer lid. In certain embodiments, the protrusion of a juicer lid is surrounded by a recess where juice may collect, preferably with a hole at the bottom of the recess. Surrounding the recess of a juicer lid, in certain embodiments, is a collar that may rest in the opening of a beverage container on which the juicer lid is used, and which may form a seal with the beverage container. In certain embodiments, a juicer lid may be placed on a beverage container with the protrusion pointing outward for generating juice. In certain embodiments, a juicer may be placed on a beverage container with the protrusion pointing inward the container, so that the opposite side, without a protrusion, is exposed, allowing the removal of fluid from the container through a hole, for example by drinking from the hole. In certain embodiments, equilibration of air is facilitated through a second hole. In certain embodiments, a juice lid of the invention may be secured onto a beverage container in either orientation, protrusion outward or inward, for example through a screw on ring.

Lids according to certain embodiments of the current invention are further exemplified in the figures. In FIG. 1 there is shown a lid according to certain embodiments that is of an overall circular shape with a molded protrusion 1 and 2 at a non-parallel angle away from the plane with the fat-lip 6, where it can be secured with a screw clamp 10, as shown in FIG. 8. A flat lip 6 extends around the periphery of the lid depending from a circumferential ridge 5. A lid according to the invention may be made of metal, plastic, or any other sufficiently durable material, for example a one piece thermoplastic structure or some other thermo-formable material suitable for use with beverages. The opening 3 is used to remove liquid from the container and the opening 4 facilitates equilibration of air in the vessel. In certain embodiments, a lid of the current invention does not have a protrusion 2, an opening to facilitate equilibration of air 4, a fat-lip 6, and/or a circumferential ridge 5.

FIG. 2 shows a lid according to certain embodiments; the transverse line A is where the cross section of the lid is shown in FIG. 3. The lid of FIG. 3 again shows the front facing spout 1 in cross-section, tapering along the outer edge of the lid to a lower raised annular section 7 of the lid. FIG. 4 shows another view of a lid according to certain embodiments of the invention. Shown are a molded protrusion, a hole for removing fluid 3, a hole to facilitate air flow and equilibration 4, a ridge 5, a fat lip 6, and a lower raised annular section 7. In certain embodiments, a lid of the current invention does not have a raised annular section 7.

FIG. 5 shows the underside of a lid according to certain embodiments of the invention with a hole for removing fluid 3, a hole to facilitate air flow 4 for equilibration, a ridge 5, a fat lip 6, and a steeper ridge 8 (steeper than ridge 5). The equilibration hole 4 is shown in the centrally located depression of the lid. The ridge 8 demarks an increase in the angle between the spout and the immediately adjacent circumference of the lid, while the ridge 5 demarks the transition to a portion of the lid specifically designed to engage the lip of a jar while in compression from a screw-on ring. The drinking spout on the lid features an opening 3 from which a person can consume liquid. FIG. 6 shows the upper side of a lid according to certain embodiments of the invention with a hole for removing liquid 3, a hole for air flow 4, a ridge 5, and a fat lip 6.

It will be recognized by one skilled in the art that in addition to Mason jars other jars may be used with a lid according to the invention, including but not limited to Kilner jars, fruit jars, mouth-blown canning jars with and without a ground rim, bead sealed jars, shoulder sealed jars, continuous external screw thread jars, quart jars, half-gallon jars, groove-ring type jars, Hemingray jars, Improved Masons, rim sealing jars, straddle-lip top seal jars, jars with a screw thread finish, narrow mouth jars, and external screw cap jars.

A lid of the current invention can be used with a beverage container made of any material. For example, jars may be made from soda-lime glass or plastic. A lid of the current invention may be used with a jar of any dimension, for example, a regular mouth canning jar with a 2⅜″ (60 mm) diameter opening, or a wide mouth canning jar with a 3″ (76 mm) mouth diameter opening. A lid of the current invention may be used with a beverage container of any size, for example, from a few ounces to half a gallon.

A lid of the current invention may also be used with international models of beverage containers, for example canning jars like a Kilner Jar and a Leifheit Jar, both having a 2 13/16 (72 mm) diameter opening. A metal seal disc for this type of jar is ˜3 7/16″ (84 mm) in diameter. These jars come in a variety of sizes as well, all with this mouth opening size. These jars are rated in lbs and come in 1, 2, 3, and 4 lb sizes. Some Kilner jars do not use the metal compression ring type enclosure, instead using metal clips to hold a glass lid with rubber seal onto the mouth of the jar.

Jars are generally measured by the size of the internal diameter of the mouth opening. The jar is the guide for the sizing of a lid of the current invention that may be used with the jar. Jars are also referred to as Wide Mouth, Regular Mouth, and internationally as Kilner. Jars are usually not described by the actual size of the jar due to their standardization.

Many sauce containers that can be purchased at a grocery store also have threading and standard sizing like Regular and Wide mouth canning jars. Regular and wide mouth size is preferably used with a lid of the current invention, but other sizes may be used too. These jars are typically not provided with the two piece construction canning jar lid (lid and compression ring) instead they come with a one-piece vacuum sealed lid. A lid of the current invention, in certain embodiments, may be used with a jar, or other beverage container, that does not have a screw-on ring, preferably by using a screw-on ring from another container, for example a jar. This is generally feasible since the openings of beverage containers like jars are generally one of a few uniform dimensions, for example, a regular or wide mouth jar. Therefore, a screw on ring from one container like a jar can be used on another container with an opening of the same dimension.

In addition to screw-on rings, the clamping mechanism for use with a lid of the invention may be a screw-on band, a compression ring, a two part compression ring, a compression band, a two-part compression band, an external threaded screw cap, a screw clamp assembly, and a screw-top lid, or a means for compressing a lid to the lip of a jar.

In certain embodiments of the invention, methods are provided for covering a beverage container with a lid of the current invention and for using a beverage container with a lid of the current invention. A method of the current invention, in certain embodiments, comprises placing a lid of the invention on an opening of a beverage container, for example a jar, and attaching the lid to the beverage container, for example through a screw-on ring. In certain other embodiments, a method of the invention comprises using a beverage container with a lid of the current invention for consuming a beverage.

In certain embodiments of the invention, methods are provided for dividing a beverage container with a bento box separator of the current invention and for using a beverage container with a bento box separator of the current invention. A method of the current invention, in certain embodiments, comprises inserting a bento box separator of the invention into an opening of a beverage container, for example a jar, and closing the beverage container, for example through a screw-on ring. In certain other embodiments, a method of the invention comprises using a beverage container with a bento box separator of the current invention for transporting and/or consuming a beverage or food item.
